Answer:
Solution given:
Cos -θ:[tex]\frac{\sqrt{3}}{4}[/tex]
since cos -θ=Cos θ
Cos θ :[tex] \frac{\sqrt{3}}{4} [/tex]
[tex]\frac{\sqrt{b}}{h} [/tex]=:[tex] \frac{\sqrt{3}}{4} [/tex]
b=[tex]\sqrt{3} [/tex]
h=4
p=[tex] \sqrt{4²-(\sqrt{3})²} [/tex]=[tex] \sqrt{13}[/tex]
So
Sin θ=[tex]\frac{p}{h} [/tex]=[tex]\frac{\sqrt{13}}{4} [/tex]
So third one is a required answer.

Which represents the solution set to the inequality 5.1(3 + 2.2x) > –14.25 – 6(1.7x + 4)? x < –2.5 x > 2.5 (–2.5, [infinity]) (–[infinity], 2.5)
Answer:
x > -2.5 (-2.5, infinity)
Step-by-step explanation:
Given the inequality expression
5.1(3 + 2.2x) > –14.25 – 6(1.7x + 4
Expand
15.3 + 11.22x > -14.25 - 10.2x - 24
15.3 + 11.22x > -38.25 - 10.2x
Collect the like erms
11.22x + 10.2x > -38.25 - 15.3
21.42x > -53.55
x > -53.55/21.42
x > -2.5 (-2.5, infinity)
This gives the required solution
Answer:
(-2.5, infinity)

In a blind taste test, 25 people chose brand A, 15 people chose brand B, and 10 people chose
brand C. There are 200 more people to be surveyed. Based on the data, which is most likely.
to happen?
About 10 more people will choose brand B than brand C.
About 30 more people will choose brand C.
About 30 more people will choose brand A than brand B.
About 100 more people will choose brand A.
Answer: About 100 more people will choose brand A.
Step-by-step explanation:
Number of people who chose brand A = 25
Number of people who chose brand B = 15
Number of people who chose brand C = 10
Total number of people = 25+10+15 = 50
Since there are 200 people left, we'll equate them based on the data given and this will be:
For A = 25/50 × 200 = 100
For B = 15/50 × 200 = 60
For C = 10/50 × 200 = 40
Therefore, about 100 more people will choose brand A.
Answer:
About 100 more people will choose brand A

The ratio of mass of kangaroo to the mass of a penguin is 7:2. The kangaroo weighs 56 kg. What is the mass of penguin?
Answer: 16
Step-by-step explanation:
I think my answer is correct because, if kangaroo is 56 kg and the ration kangaroo to penguin was 7:2 I think we just have to divide 7 by 56. And 56 divided by 7 equals=8. and Since the pengiuins ration is 2 we just have to multiply 8 and 2. And 8 times 2 equals 16.

9. P(A and 5)
11. PJ and less than 3)
13. P(consonant and odd)
14. P(M or T and greater than 3)
Answer:
9) 1/48
11) 1/24
13) 5/16
14) 1/8
Step-by-step explanation:
9) P(A and 5) = 1/8 × 1/6
11) P(J and LT 3) = 1/8 x 2/6
13) P (consonant and odd) = 5/8 x 1/2
14) P ('M' or 'T' and GT 3) = [(1/8+1/8) × 1/2] = 2/8 x 1/2

What is the area in square centimeters of the trapezoid below
Answer:
area = 1/2(a+b)h
a= 8.2 cm
b= 22.9 cm.
h= 9.8
therefore area = 77.91 sqcm
The area in square centimeters of the trapezoid below is 77.91 .
How to find the area of a trapezoid?The area of a trapezoid is the half of the product of sum of its parallel sides to the height of that trapezoid (the distance between those parallel sides).
Thus, if we have Length of its parallel sides = 'a' and 'b' units respectively
Perpendicular distance between its parallel sides = 'h' units,
Area = 1/2(a+b)h
a= 8.2 cm
b= 22.9 cm.
h= 9.8
Area = 1/2(8.2 + 22.9)9.8
therefore, area = 77.91 sqcm

Answer:
100 π
Explanation:
Since the equation for the area of a circle is π r^2, and the diameter is 20m. There is enough info to proceed.
First, half the 20m to 10m since the radius is 1/2 of the diameter.
Next, plug this into the formula to get the answer:
π 10^2
π 100
100 π is the answer, since it is looking for it in terms of π.

Let A be the set of all strings of decimal digits of length 5. For example 00312 and 19483 are two strings in A. You pick a string from A at random. What is the probability that the string has no 4 in it
Answer:
0.59049
Step-by-step explanation:
Set of all digit strings of length 5
Digit range = (0 - 9) = 10
Length of digit = 5
Total possible outcomes = 10^5 = 100000
String without a 4 ;
Digit range = (0,1,2,3,5,6,7,8,9) = 9
Length of digit = 5
Required outcome = 9^5 = 59049
Required outcome / Total possible outcomes
59049 / 100000
= 0.59049
Collete mapped her vegetable garden on the graph below. Each unit represents 1 foot. Collete plants an 8-foot row of lettuce in the garden. Which points could tell where the row of lettuce starts and ends?
Answer:
(-4,-1) and (-4,7)
Step-by-step explanation:
If Collete planted a row of lettuce, that means their coordinates must have the same vertical coordinate, or the same horizontal coordinate. Another important characteristic is that between those points, there must have 8 units of separation, because it's an 8-foot row.
